Unique URL per respondent PLUS Consent form PLUS Anonymous Survey

I'm trying to set up a survey that ensures that respondents can't answer more than once, that also has an IRB Approved Consent form, which I understand I can then redirect consenting respondents to another survey (the questions in my study).

I'm getting stuck on the set up that only allows one response and how to ensure only responses from that link can be redirected to the second survey.

@Emd2020 it sounds like what you are doing is trying to create an anonymous survey WITH an identifier to let you know who submitted the survey (which would no longer make it anonymous). You have to pick one or the other. You can't have anonymous while also tracking how many times a respondent responds unless I misread your question.
